I have trained as good many times, but PayPal messages continue to get identified as spam. My installation is very plain (no custom filters; only smart mailboxes and no moving of messages outside of SS).
I’m attaching screenshots of the whitelist and blocklist. I’m not expert enough to know if fixing this issue might simply entail checking the checkboxes that are currently unchecked … any advice and instruction would be welcomed!
